To aZZ whom it may concern: I E is the nail-carrier.

Be it known that I, FREEBORN F. RAYMOND, e isthe nail-carrier slide, towhich the nail- 2d, a citizen of the United States, residing at carrieris secured.

It is adjustable orhead, last, and work in this position during removable from the table 6.the driving of the nails,and then immediately permits the quick downwardmovement or descent or fall of the pressure-head and work, this downwardmovement of the pressurehead being facilitated by the springs O. Thisdownward movement is immediately followed by another quick upwardmovement without rest, upward movement, and downward movement, therebeing no appreciable rest between the last upward and downwardmovements. The machine then stops. It will be seen that the firstdownward, second upward,and downward movements take place during themovement of the cross-head from its lowest position to just beyond itshighest position when at rest. Upon the first downward movement of thepressure-head and work the top-lift-spanking plate F, carrying the toplift, if it is desired to blind-nail the top lift, is moved rapidly intoposition from one side of the boot or shoe or work-support over it, thecam f being constructed to provide the plate with this movement and alsoto hold it there for an instant during the secondupward movement of thepressure-head and work until the pressure-head and work have fallenslightly or sufliciently' to permit the reverse movement of thetop-lift-spanking plate and its return to its original position. The toplifts may be placed in the toplift holder by hand or fed thereto by afeedplate moved automatically or by hand. The nail-carrier E isimmediately moved forward upon the starting of the machine and comesinto position to deliver its nails to the holes of the templet beforethe drivers enter its holes, and upon the upward movement of thecross-head immediately after the ends of the drivers clear or leave itsholes its operatingcam moves it backward to a position to be filled withnails. The nails preferably are fed to it by automatic nail distributingand feeding devices similar to those described in various of my patents.The cross-head A is moved downward upon the starting of the machine, thedrivers entering the holes of the nail-carrier and templet,driving thenails into the work, and then upward to its highest po sition, and thenslightly downward, when the machine comes to rest. By giving thecrosshead A sufficient throw, and by mounting the pressure-cam 0 uponthe crank-shaft, and by constructing it as described,and by giving thevertical shaft 6 one revolution for every reciprocation of thecross-head, I am enabled to employ cams which will permit the parts tobe moved as above specified, and to obtain very easy cams, and to wellapply the power from the driving-shaft, and to very much simplify theconstruction of the machine as compared with that shown and described inthe application referred to.

It will be understood, of course, that in this machine the heel-blank orwork is not pricked,

can be used for any kind of work to which gang-nailing is applicable.

It will thus be seen that the machine herein described embraces in acomplete organization means so combined and operated that by onerevolution of a shaft the heel-blank is compressed, the attaching-nailsdriven, the top lift fed and attached, and the parts separated to permitthe removal of the finished boot or shoe from the machine. It willfurther be noticed that to accomplish this result it is necessary thatthe last or work-support, templet or pressure-plate, and drivers shouldbe, when the machine is at rest, held separated from each other topermit the shoe to be placed upon the last and the heel to be placedbetween the shoe and the templet, and also to permit the nails, unlessthey have been previously placed in the heel-blank, to be fed to thetemplet.

Upon the starting of the machine its first action is to compressthe-heel-blank between the last or work-support and templet orpresssure-plate and to drive the attaching-nails. This is followed bythe separation of the last or work-support with the work thereon and thetemplet or pressure-plate and the introduction of the top-liftholdingand spanking plate or top-lift-spanking plate between them, andthis in turn is followed by another compressing action between the lastor work-support and templet, and this again is followed by theseparation of these two parts, so'that during the complete action of themachine, or, in other words, during the rotation of the actuating-shaft,one engagement of the templet with the drivers and two engagements orimpacts between the last or work-support an d the templet have takenplace. This organization is especially valuable in heel-nailingmachines, because it simplifies the construction of such machines andincreases their capacity.

Having thus fully described myinvention,

I claim and desire to secure by Letters Patent of the United States 1.In a heel-nailing machine, a reciprocating cross-head carryingheel-attaching devices, a templet or pressure-plate, a last orwork-support, a cam on the crankshaft for giving the latter two impactsand periods of separation during one revolution of the shaft, and atop-lift plate and mechanism for moving it between the templet orpressure-head and the work when separated substantially as described.
